FIRE RESISTANT THERMOPLASTIC-BASED RESIN FOR FIBER-REINFORCED COMPOSITES

A first composition is disclosed that includes a fire-resistant thermoplastic resin. The fire-resistant thermoplastic resin includes 1-20 wt % of an aryl phosphate, includes 1-20 wt % of a phosphate polymer, and 60%-98% of a (meth)acrylic polymer, including units from at least one monomer, wherein the monomer is chosen from methyl methacrylate, acrylic acid, methacrylic acid, acrylic acid esters, methacrylic acid esters, acrylonitrile and maleic anhydride. The first composition may further include a fabric or a composite material that is embedded with the fire-resistant thermoplastic resin. In some instances, the aryl-phosphate and the phosphonate polymer synergistically reduce an effective heat of combustion, a peak heat release, or a flame time as compared to a second composition that contains only one of the aryl phosphate or the phosphonate polymer.

Polyester film comprising a polymeric phosphonate flame retardant

A polyester film comprising a polymeric phosphonate flame retardant in an amount of from about 1.0 to about 25.0 wt % by total weight of the film and further comprising at least one metal cation selected from the group consisting of Group I and Group II metal cations.

Self-cooling foam-containing composite materials

Provided herein is a composite material that includes at least one thermoresponsive polymer and at least one organic foam material. Further provided herein is a method for producing the composite material and also to the use of the composite material for cooling and for regulating temperature.

Polyisocyanurate Foams with Flame Retardant Properties and Process for Making the Same
20210395433 · 2021-12-23 · ·

This disclosure provides for new polyisocyanurate (PIR) foams that exhibit improved flame retardant properties and thermal barrier properties, and which can pass certain thermal barrier tests in the absence of a protective covering such as specified in the thermal barriers codes. In an aspect, it has been unexpectedly discovered that when a relatively high viscosity and high functionality polyisocyanate is used with a high aromatic content polyester polyol and an HFO and/or HCFO blowing agent, and a flame retardant compound, unexpectedly good flame retardant polyisocyanurate foams can be generated, for example, when a high A-side:B-side volume ratio (v:v) and a relatively high Isocyanate Index (ISO Index) are used in the process.

POLYESTER FILM COMPRISING A POLYMERIC PHOSPHONATE FLAME RETARDANT

A polyester film comprising a polymeric phosphonate flame retardant in an amount of from about 1.0 to about 25.0 wt % by total weight of the film and further comprising at least one metal cation selected from the group consisting of Group I and Group II metal cations.

Nanoparticle containing compositions

Flame retardant compositions, blends and articles include phosphonate polymers, nanoparticles and optionally dispersing agents. A method for preparing such retardant composition, blends, and articles is also presented herein.

FLAME RETARDANT CONTINUOUS FIBER REINFORCED THERMOPLASTIC TAPE

A continuous fiber reinforced thermoplastic (CFRTP) tape is disclosed, made of continuous, unidirectional glass fibers embedded in polyethylene terephthalate glycol modified (PETG) containing a polyphosphonate homopolymer non-halogenated flame retardant (NHFR). With formulations balancing the spread of flame and the detection of smoke, the tape achieves a Class A value when tested in accordance with ASTM E84.
